When a medical emergency occurs at sea, the actions taken in the first few minutes directly determine the victim’s survival.
This is especially true in cases of sudden cardiac arrest: on-site first aid is urgent, yet professional medical rescue often takes hours to arrive.

Against this backdrop, equipping vessels with Automated External Defibrillators (AEDs) as a practical emergency preparedness measure can significantly enhance a ship’s emergency response capability and save lives, attracting increasing attention from the industry.
Why the Automated External Defibrillator (AED) is Crucial
The Automated External Defibrillator restores the heart’s normal rhythm for specific types of cardiac arrest by delivering an electric shock. New-generation devices are simple to operate and moderately priced, requiring only basic training for operators.
The device automatically assesses the patient’s condition and prompts the rescuer whether and when to deliver a shock, making it operable by ordinary rescuers with basic training, including crew members.
The UK Maritime and Coastguard Agency (MCA), in its Marine Guidance Note MGN 297(M) Amendment 2, recommends that ship operators conduct a risk assessment (with external professional assistance if necessary) to determine whether a vessel needs to be equipped with an AED.
The UK Maritime and Coastguard Agency specifies that the assessment must consider the following factors: total number of persons on board, crew-to-passenger ratio, age structure of persons on board, and any additional risk factors that increase the probability of cardiac disease.
The Critical Importance of Early Defibrillation
Clinical medical conclusions are very clear. The UK Maritime and Coastguard Agency states that the highest success rate for resuscitation is achieved when defibrillation and supporting first aid are completed in the shortest possible time, ideally within three minutes of the onset of the cardiac arrest.
For every minute defibrillation is delayed, the probability of successful resuscitation decreases by at least 10%, making it crucial to have an AED readily available on board at all times.
This issue is particularly acute for seafarers: ships are among the most resource-poor and isolated working environments regarding medical care.
MarinePALS calls for mandatory AEDs on all merchant vessels, emphasizing that cardiovascular disease remains a leading cause of death at sea;
during the golden window for resuscitation following a cardiac arrest, often only crew members can provide first aid.
Captain Pradeep Chawla, CEO of MarinePALS, calls on the shipping industry and regulators not to view defibrillators as an optional extra, but as a fundamental life-saving facility that must be implemented.
Gradual Regulatory Attention to AED Provision in Various Countries
The Malta Transport Authority also strongly emphasizes the importance of equipping ships with AEDs.
Its Merchant Shipping Notice No. 198 states that while current international maritime regulations do not mandate AEDs on ships, protecting the life and health of seafarers and passengers remains the core of regulatory work.
The notice strongly recommends that passenger ships and vessels operating beyond the Global Maritime Distress and Safety System (GMDSS) Sea Area A2 conduct risk assessments to determine the need for AEDs.
The Malta Transport Authority further requires that vessels flying the Maltese flag be equipped with at least one Automated External Defibrillator suitable for the harsh maritime environment.
Simultaneously, the regulatory body proposes four practical requirements for equipment procurement and placement:
The equipment must be robust and waterproof;
Stored in a clearly marked, easily and quickly accessible location;
Ensure all crew members are proficient in its operation through regular emergency drills;
Include battery life, electrode pad integrity, and overall device functionality in the vessel’s routine maintenance inspection schedule.
Supporting Training, Equipment Maintenance, and Telemedicine Support
However, equipping an AED is only one part of a complete first aid process.
Crew members must simultaneously receive specific practical training in AED operation and Cardiopulmonary Resuscitation (CPR), with regular refresher training to maintain practical skills.
Furthermore, the master and ship operator must ensure all personnel are familiar with the telemedicine consultation procedure; once a defibrillator is used for rescue, arrangements for personnel evacuation must be made immediately to connect with subsequent professional medical treatment.
A Practical Investment in Safeguarding Seafarer Welfare
Ultimately, an AED cannot replace a professional physician’s diagnosis and treatment. However, given the unique environment of the shipping industry, where distance and time often delay professional rescue, an AED empowers crew members to seize the critical intervention window before shore-based medical resources arrive.
Therefore, proactively equipping vessels with Automated External Defibrillators is a practical investment in improving maritime emergency response, safeguarding seafarer welfare, and protecting life safety at sea.
